Plastic Waste Recycling: Experiences, Challenges and Possibilities in a Circular Economy-A State-of-the-Art Review
Worldwide, plastic products are essential items, transforming our everyday life. Demand and usage are gradually increasing. Subsequently, plastic waste generation also increased to 287 million tonnes in 2019. Despite several benefits from plastic products, the mismanagement of plastic waste and its detrimental effects on the environment, living species, and nonliving element is a global concern. The waste plastics are the cause of great nuisance. Recycling waste plastics is one of the best solutions to get rid of the pest. On the other hand, 4% of petroleum resources worldwide are used for plastic production. Many technologies have been introduced to recycle plastic waste in different applications such as energy generation, secondary plastic production, construction materials, road construction, composite materials, and others. Proper management of plastic waste through the circular economy principle is one of the sustainable approaches to increase the recycling possibilities of plastic waste in different productive applications leading to replenishing the depletion of natural resources, reducing the harmful effects on the environment, and improving sustainability in the plastic industries, at the same time policy formation is essential to control the mismanagement and misuse of plastic waste throughout the globe. This article has explored plastic waste recycling and application possibilities in a circular economy, replenishing nonrenewable resource depletion, reducing carbon budget, environmental pollution and increasing sustainable development.
